This is a crossbar plaque1.16m long and 0.34m wide. There are four cursive characters "Fei Yi Chen" in the middle of the plaque. The upper right corner of the plaque is engraved with the seal of "living on wood and stone", and the left side is engraved with the word "Tianchi" and two famous seals with the words "Seal of Xu Wei" and "Tianchi" written respectively.
These inscriptions and seals were written and sealed by Xu Wei himself. It is said that Xu Wei was a legendary scholar in Ming Dynasty. He was brilliant all his life and made outstanding achievements in books, poems and paintings. However, he was proud and self-disciplined in the ideal realm of "no less than dust" all his life, which made his life very bumpy and eventually unhappy.
His inscription of "not a speck of dust" is vigorous, dry and moist, which shows his noble character of "not a speck of dust" to refuse dignitaries.
In addition, in his library, besides this plaque inscribed by him, there is also a plaque inscribed for him by Chen Laolian, a great painter in the late Ming Dynasty. Although this tablet has a history of more than 300 years, it is still very clear, and it is also a masterpiece of China's calligraphy in the Ming Dynasty.
